METHOD OF MAKING PLATED WIRE.

SPECIFICATION forming part of Letters Patent No. 663,344. dated December 4, 1900.

Application ledNovember 28, 1899.

T0 all whom t may concern:

Be it known that I, JOHN T. HEALY, a citizen of the United States, residing at Attleborough, in the State of Massachusetts, have invented a newr and useful Improvement in Methods of Making Plated Wire, of which the following is a specitication.

My invention consists in the improved method of forming the ingot from which the wire is to be drawn.

In the accompanying drawings, Figure l represents a longitudinal vertical section of the prepared ingot. Fig. 2 represents an end view ot the same.

In the drawings, A represents a seamless tubular core of basemetal, and B represents the exterior covering ot precious metal, the said covering being made of a sheet of precious metal beveled or thinned atits edges and lapped around the core, as shown in Fig. 2, a suitable fiuX being placed between the contact -surfaces7 and outside of the precious metal is placed a circumferentially-arranged sheet of asbestos or paper O, and outside of this sheet is placed a spiral Winding of at wire D, and in carrying out my invention the Serial No. 738,570. (No specimens.)

ingot so formed is subjected to such a degree of heat as to cause the contact-'surfaces of the base and precious metals to sweat together. The ingot may then upon the removal of the Winding of Wire and the sheet of asbestos or paper be subjected to the Wire-drawing operation for the production of a seamless Wire.

The core A may be made solid instead of hollow, if it is desired to make a solid Wire.

I claim as my invention- The method of making an ingot for the manufacture of seamless plated wire, which consists in applyinga sheet of-precious metal having its longitudinal edges thinned or beveled and lapped upon each other, to the surface of the base-metal ingot, with a suitable flux between the contact-surfaces, applying a thin covering of sheet asbestos or paper, and then winding with wire, and subjecting to the proper degree of heat to cause the sweating together of the contact-surfaces of the base and precious metals, as set forth.

JOHN T. HEALY.
